TO,A LL WHOM IT MAY'CONCERR Be it known that I, WILL-mar H. Joimsox, of Springfield, in th-ecounty of Hampden, and State of Massachusetts, have invented a new and useful Machine for Cutting Pieces to Form from leather, cloth, paper, and other similar materials, and embossing the same; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-- Figure 1 is affront elevation,

Figure 2 is a. side elevation,

Figure 3 is an elevation of-the opposite side,

Figure 4 is a vertical longitudinal section, and

Figure 5 is asectional plan.

The same letters refer to the same parts in all the figures.

The subject-matter of my invention consists of certain improvements in machines for embossing and cutting pieces to form from a web or'sheet of cloth, paper, leather, metal, or other similar material which may properly be submitted to'its action. and .is herein shown embodied in' a machine arranged for cutting paper collars from two webs of paper. a

My invention relates, in the first place, to the manner of constructing and using the cutters by which the object is cut toform, and'consis'ts in the employment of a cutter which has 82 cutting-edge, or an edge that 'cuts byincision, in combination withn hard surface, as hard as or harder than the cutter, against which the edge of the cutter is forced, and by their contaotthe material to be cut is severed,

'My invention relates, in the second place, to the manner ofcombining and arranging the machine so as to simultaneously cut and emboss two collars or other objects from two webs or sheets and consists, first, in placing between the bed and platen, that carry thecutting-apparatns, and in proper relation tothe said cutting-apparatus,

a duplex embossing-die, placed between the webs or sheets, and having a wbrking-fnce on either side thereof toward the sheets, in combination with two counterpart-dies or matrices placed outside the sheets upon the bed and platen, by which means both sheets of material will be embossed by one impression; and it cons'ists, second, in the employment, between the bed and platen, and also between the sheets of material to be embossed, of a thin plate, covered with some slightly-yielding material like cloth, if necessary, in combination with a pair of embossing-dies, placed exterior to the Webs, and opposite to each other on the bcdand platen and forced against the material by the impression; 'the first-mentioned combination, being used in the machine shown, is to emboss the folds of collars, and the last to emboss the semblance of stitching; and it consists, third, in thcmanner of arranging and combining, in a machine for cutting collars, the cutters which cut the collars to form, the button-hole cutters, the dies that emboss the folds, and the dies that cmboss the stitching, in connection with the other essential parts of the machine, by which one or more finished collars are formed at each revolution of the main shaft. v

My invention relates, in the third. place, to the manner of constructing the connecting-rod or pitman, which forces the platen against the bed, so that its length may be n'icely adjusted to adjust the pressure without disturbing the bearings, and consists in forming the pitman in two parts, united by a top ofl'set-joint, secured together by bolts, and between the ofi'sets of which a taper-key is inserted, by means of which the pi'tman may be lengthened or shortened to adjust the same, and, at the same time, be unyielding.

Inthe drawings, A-is the frame of the lower portion ofthe machine, across the top of which is placed the bed-plate B. On the bed-plate are erected the standards A A, which support the cross-beam A, the whole being firmly bolted together by the tie-bolts a a.

C is the main driving-shaft, from which all the necessary movements are derived to operate the machine. The shaft 0 issupported in the bearings 11 b, projecting downward from the cross-beam A, as shown. D is the driving-pulley, by means of which the shaft Gis set in motion, and E is the fly or balance-wheel. having a counterbalance-weight, E", attachedto it, the purpose of which is-to enable the operator to stop the machine at any desired point in the revolution of; the erauk-shaft without danger of accident, by. the falling" of 'the platen, while the dies are being-put in. v

The shaft 0 is also provided with a'orarik, G", near the centre of itslength, for the purpose of operating the platen F, to which it is attached by means of the connecting-rodor pitman G. .The platen F is guided in its vertical movement by means of the-long guide-pieces F,'formed .on the-same, whiohwork in the guides F', formedon the standards A A, and provided with gibs e c and gilt-screws d d, by means of which the'wear of the parts may be takenup, and the platensmay be adjusted laterally,-if necessary. It may also be adjusted in a vertical direction, by increasing or diminishing the length of the connecting-rod G, which maybe very readily accomplished by means of the key H and holding-bolts I I; the connecting-god being made in two parts halved together,xas shown, and bolted together by said bolts, the'bolt-holes being sletted in one of the parts, so as to allow of the parts being-forcedapart', by the lreyH, which is inserted between the ofi'sets on the two parts of the conneeting rod, as shown, when the nuts'of the bolts I have been slackened, or moeversa.

The platen F has a recess in it, into which the half box J is..fitted, di'reotly under the lower end of the connecting-rod G, and .in which it vibrates as in a soclret as thecranlz revolves. The connecting-rod'G'has a steel pin, e, fitted into it, concentric with the curve of its lower end, and projecting from either side asuflicient distance to receive the half box f on its upper side,-with the cap g over it," which is bolted firmly to the platen.

F, thus attaching the connecting-rod to the platen in such-a manner that any wear of the pin or boxes may he easily-corrected. i I

' The bed-plate Bhas a larg'ehole'cast in its centre, 'as shownin fig; 4 0.4 the top of and bolted totthe bed-plate B is the die-bed K, having such openings through it'as ,n 1ay be required to allow the portion'of material cut out to pass through, and being strongly ribbed oh its under side around said openings.

L is the lower die-plate, towhich are attached the cutter It, the buttonhole cutter z, the lower female die j for embossing the folds of the collars, and the lower stitch-embossing-die k.

Attached to the under side-of the platen F is the upper. die-plate L, to which are attached the stitchembossing die k' ,the upper femaleidie j" for embossing the folds of the collar, and thetwo .hardened steel platesi andhfl against which the cutting dies act to cut the material. i

The cutters It ends are made of steel, with an opening through them of the fo'rm of the article to be out; the opening being largest at the bottom to allow the piece of materi'al'cut out to drop through themv into a receptacle placed below. i

The'upperedges of the cutters are ground tea perfectly level surface, as are the hardened-steel plates 7:,- and i so that when the platen is moved down, so -as to bring thesteel plates hi and e" on to the cutters k and i,

there shall be practical eontact'over the whole surface ofthecnttiug-edges. The hardened steel plates It and 2 will serve for any. form of die, 'the outlines of. which 'do'not estend beyond the limits of their surfaces. The cutters are then ground on the outside with it-bevel, as shown, to' nearlyw. knife-edge, but having a percep. tible thickness ofmctahsay, about one-hundredth of'an inch at the extreme edge. The hardened-steel plates and the cutters should riotjhave any lateral or. sliding motion on each other, as that would break the edge of the cutters. v

M and N are ca'ms, which operate the feed-works. M"a'nd Il'are plates or bars, having a vertical sliding motion in bearings] and Z' on the standards A A, and operated by the cams M and N.- O is a rocker-shaft, mounted'in suitable bearings in the frame A, and carrying on its outer ends the arms 0', which are connected at their upper ends, through the medium of thelinks P, to the foe'd-rod P'. ,At or near one end of the rocker-shaft -O is also firmly attached the, arm Q, containing the curved slot Q, by means as which thelinl: Qf, attached by its-upper endto the plate M, may be adjusted, so as to vary the amount-of vibration ofjthe rockershaft O,

and thereby increase or diminish,- at pleasure, the amount-oi feed g'iveu'to themat erial to be' out.

The cam M, the sliding plate M, the rocker-shaft O, the armsO and Q, and the links P P and Q, serve to give a forward and, backward motion to the-feed-rod P, and thercby, through. its connection with the fced-n ippers, to behereafterv explained, to fecd the pappr forward a given distanee ut 'cvcr'y revolution oi' the machine. 1

its outer ends the radial guide-rods S and the arm T, which is connected to the sliding plate'N' by means of the adjustable link U, all of which servethe purpose of lifting the-materia'lpfi' from the dies while'it'is being fed forward. V j p v The front ends of the radial guide-rods S S are tied together bythe truss-tie rod V, to which is. attached,

\ near the centre of its length, the adjustable stop m: Each of the radial guide-rods S S is also provided with two adjus-thble tubular stops n n, which stops serve the purpose of limiting the movemei it of the feed-rod P in either direction, and thereby insure a greater 'degre e of accuracyfto the fecdingof the material than could otherwise be obtained.

The sheet-metal plate W is attached. to the rocker-shaft R at or near its rear ehd, and extends forward nearly tothe stitch-embossing dies, and has two guide-bars o 0, attached to its upper side by means of bolts passing through slots in the plate W, so that the giiide-bars may be adjusted'to fit difierent'widths of material.

The guide-bars o o hare rectangular-shaped grooves p 11 formed in their under sides, which form bearings for the rear ends of the nipper-bars q .q, and infwhich they-are moved forward'and"back'lby the feed-rod P, to which they are attached, at their forward ends, in such a manner that they may be-adjusted in connection with said. bars, to any width of material. j

' The nipper-bars q q.hare lips rr projecting from their inner sides, which form the lower or fixed jaws hf the fe'ed-nippers. The movable jaws as are attached to the nipper-bars q g by the fulcrum-pins; t, and are I}. is a rocker-shaft, supported in suitable bearings holtedto the back end of the machine, and carrying at operated to clamp or release the material to be fed, by the vibratory motion of the bar it around the feed-rodj P, upon which it is hung, which motionis obtained from the movement of, the'upper end o t'the pitman or connecting-rodG, by means of the curved'arm or leverv and the adjustable curved link w.

On theforward' end of thesheet-metal plate W, and just in the rear of the dies, is placed the spring 2:, on which rests the. curved pressure-plate y, over which the material to'be out passes, and by which it is-raised above the dies when the platen is movedlup, and holds the material up to the plate'while it is being fed forwaird. To enable me to emboss theimitation of stitching on the collars or other articles at the same time, I interpose between the two stitch-embossing dies, attached to the bed and platen, a sheet-steel plate, Z, enclosed in a covering of cloth or other yielding material, and between the two sheets of paper or other material to he-operated upon, so that, when the platen is moved down by the revolution of the cranlt, so as to submit thematerial ,k to pressure, the action of the two stitch-embossing dies, whose working-faces are towards each other, are also i toward the steel plate Z, shall emboss an imitation of, stitching on the under side of the lower sheet-or web of material, and on the upper side of the upper sheet or web. i

To enable me to emboss the line of fold in two sheets of material at the same time, I place between the two sheets the duplex die or rib a, having its upper and lower edges alike, and curved to correspond to the grooreildicsattached to the platen and bcd, so that, as the platen is moved down, said rib or blade is forced into the paper or other'matcrial, and the material is forced into the female or grooved dies jandf, and embosses a line across each sheet of material in the position for folding the collar. p

The duplex (lie or rib a is attached to the skeleton frame 5 which is connected to the sheet-metal plate W, and'is held in position, with relation to itsfemale dies, by means of the adjustable forked bearingsor lugs m.

The spring-plate 0, attached to the bar :2, at therear end of the machine, by means of the sockets c and the set-screw f, serves the purpose of a friction-plate,'and, in connection with the plate 3 and spring 2, attached to the sheet-metal plate W, and placed under the sheet of material, acts as a drag on the material while it is being fed forward by the nippers, and thereby presenting a smooth surface to the action of the dies.

The lever X and link Y are for the purpose'of conveying motion to the apparatus for unwinding the material from the roll, which may be accomplished in several well-known ways. i i l The guide-bars o o and the nipper-bars q q are so arranged that they may be readily adjusted to" adapt the machine to cutting from difierent widths of material; v v V A The motion of the feed-rod P and the nipper-bars q q in a horizontal direction, and cbnsiequently the, feed of the material, may be increased or diminished at pleasure,'by means of the curved slotted arm Qand the link Q, when it is desirable to out a wider -or narrower collar, in which case the cutting and embossing-dies will be arranged on their plates at a gr'eater or less distance from each other, while the pad containing the steel plate Z will be adjusted to ag e with their accompanying dies.

The operation of machine is as follows: I a 1 The free ends of the two sheets or webs of paper, or other material to be cut, are drawn into the machinein the position shown by the red lines in fig. 4, until they are inserted between the jaws of the feed-nippers, the two sheets passing under the bar 11, and between it and the plate W, and in contact with each other, tillthey arrive at the plate Z, when they are separated, the lower one passing under the plate Z, and between it and the plate 3 also under the duplex die or'blade a, then passing over the button-hole collar cutters till it reaches the nippers. The upper sheet passes over the plate Z, and between it and the spring-plate c, and over the duplex die or blade a, where it again comes in contact with the lower sheet.

The ends of the two sheets being placed between the jawsof the nippers,-and the machine being set in motion, the cam M begins to act upon the sliding plate M, and, through the intervening links and arms, the motion is conveyed to the' rod 1?, to which the nipper-bars are attached, and, as thefvibrating-bar U isin such position as to force the forward end of nipperdeve'r or jaw in an upward direction, the rear end-will be firmly pressed on to the material; and as the feed-rod P is moved forward, the material will be-moved forward with it;

Just as'the forward movement of the feed-nippers is completed, the cam N begins to act on the plate N; and, through the link U and aim T and radial guide-rods S S, to lower the material till it rests on the die,-at which point the platen comes in contact with it, and a very slight continuation of the motion of the shaft forces the cutter it through the paper, cutting out two collars; and .at' the same time the cutters i cut the button-holes c in the next two succeeding collars, while the duplex die or blade a, between the two sheets, has forced the material into its corresponding female dies, and embossed a curved line across each sheet, at the proper point for the fold of the next succeeding collars, and the imitation of stitching is embossed by the stitching-dies acting upon the top and bottom of the two sheets, with the steel plate Z between them.

As soon as the platenhasarrived at its lowest position, the aotion'of the upper end of the pitmau or conuecting-rod,'while passing the dead-centre, serves to open thenippers and release .them from the paper,at which point the action of the cam M upon the feed-rod P moves the nipper's back to the point from which they started at the commencement of the revolution, and in' readiness to take a now hold upon thelpapera While the platen is approaching its highest position, the camN is acting, through the plateN", link U, arm' T, and rocker-shaft R, upon the radial guide-rods e s, to raise the paper from the dies, so that it may be again fed forward.

' During eachsuccessive revolution of the machine, thesame movements-take place, the feed-works feeding a the material forward a distance equal to thewidth of the collar cut, and the width of the wastethat is found I desirable to leave between the collars. l I

The collars that are cut in any revolution of tho-machine are the ones in which the button-holes were cut in the next previous revolution but one, and the buttou-holes are cut in the collars onJlhich the folding-line was embossed in 'the'previous revolution, and so on to theend, there being flvopairs of collars in process tr mess 4 manufacture at the sometime, one pair being cut or severed from the sheet or web, one pair having their buttonholes out, one pair having the fold-lino embossed, and rue-pairhaving the imitation of stitching embossed thereon, each 'pairbeing advanced one step at each revolution ofthe crank-shaft, and one pair of collars completed and deposited in the receptacle provided for that purpose.

It is evident'that the principles of my inuentionmay he applied to other purposes than the cutting of paper collars, such as cutting articles of various forms from cloth, leather, a nd other similar material, in n hich .caso

'th e-cutting-me'chanism would be adapted to the work to be done.

What I claim as my Invention, and desire to secure by Letters Patent, is- 1. Theeombination of a cutter, having a cutting-edge of the required form, with a plain, hard surface or i plate, harder than the cutter, co-operating, substantially as described, as" a device for cutting leatherfcloth, paper, and other similarmateriai.
